Cleveland C14549 Screw Machine Drill Bit Wire 42 Cobalt

Product Description

The CLEVELAND C14549 is a screw machine length cobalt drill bit in wire gauge size 42, with a decimal diameter of 0.0935 inches. Built to heavy-duty grade from M42 cobalt steel, it features a 135-degree split point that reduces walking and improves bite on hard and abrasive materials. The web-thinned, parallel-web construction lowers thrust requirements and supports cleaner entry holes. At 1.75 inches overall length with a 0.75-inch flute, this short-length geometry provides added rigidity for high-torque drilling operations. Machinists, tool-and-die workers, and maintenance technicians install this bit in drill presses, CNC machines, and hand-held power drills.

This bit is suited for drilling alloy steel and aluminum in production environments where shorter flute length and increased bit stiffness reduce deflection and chatter. The straight-cylindrical shank fits standard drill chucks without modification. Its screw machine length profile makes it a practical choice for tight-clearance work, repetitive hole patterns, and applications where a jobber-length bit would flex or wander. Right-hand cut with regular spiral flutes handles chip evacuation efficiently in both ferrous and non-ferrous materials.

Key Features

• M42 cobalt construction rated for heavy-duty drilling in alloy steel and aluminum
• 135-degree split point reduces bit walking and lowers entry thrust
• Web-thinned parallel web improves cutting efficiency and hole quality
• Screw machine length profile adds rigidity and reduces deflection in deep setups
• Right-hand, 2-flute spiral design for efficient chip removal
• Diameter tolerance held to +0.0000 to -0.0005 inches per ASME B94.11M

Compatibility

Designed as a screw machine length replacement drill bit for wire size 42 applications conforming to ASME B94.11M and DIN 1897 standards; fits any standard drill chuck accepting a 0.0935-inch straight-cylindrical shank.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard keyed or keyless drill chuck. Verify chuck capacity accommodates the 0.0935-inch shank before seating the bit. Power down and de-energize the machine spindle before changing bits. Avoid exceeding recommended feed and speed parameters for the workpiece material to prevent premature cobalt edge wear.
